DALLAS — A Houston man has been sentenced in a nearly $3 million health care fraud case involving Houston and Dallas-area companies, federal prosecutors said Tuesday.

Godwin Umotong was sentenced to six years in prison and ordered to pay $880,000 in restitution. The 58-year-old was convicted in April of conspiracy to commit health care fraud and other charges.

Umotong and five others operated Medic Healthcare Inc. of Houston and Euless Healthcare Corp. in Hurst. Prosecutors said the defendants conspired to submit fraudulent claims to Medicare for diagnostic tests, office visits and other work. The conspiracy included recruiting unlicensed doctors to treat Medicare beneficiaries in their homes.

Others involved in the conspiracy have received sentences ranging from more than two years to 10 years.
